DEVELOPMENTS IN CLASSICAL ITEM ANALYSIS METHODS

Developments in Item Banking

Item banks can be used to develop effective and efficient systems of tests and examinations for the purposes of assessing the achievement of individual students, of monitoring changes in the curriculum and for evaluating other educational innovations. Full exploitation of the advantages inherent in the item bank concept depends on the adoption of an explicit model of test taking behaviour, such...

Using SAS for Classical Item Analysis and Option Analysis

In spite of the growing popularity of the item response theory (IRT), classical item analysis (CIA) is still frequently employed by psychometricians and teachers for its conceptual and computational simplicity. This article will introduce how SAS can be applied to CIA such as computing p-values, discriminations, point biserial correlations, and logits. In addition, option analysis, which is hel...

Developments in Black Hole Research: Classical, Semi-classical, and Quantum

The possible existence of black holes has fascinated scientists at least since Michell and Laplace’s proposal that a gravitating object could exist from which light could not escape. In the 20th century, in light of the general theory of relativity, it became apparent that, were such objects to exist, their structure would be far richer than originally imagined. Today, astronomical observations...
